The mean per capita consumption of milk per year is 140 liters with a standard deviation of 22 liters. If a sample of 233 people
salantis [7]

Answer: 0.0192

Step-by-step explanation:

Given : The mean per capita consumption of milk per year : \mu=140\text{ liters}

Standard deviation : \sigma=22\text{ liters}

Sample size : n=233

Let \overline{x} be the sample mean.

The formula for z-score in a normal distribution :

z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}

For  \overline{x}=137.01

z=\dfrac{137.01-140}{\dfrac{22}{\sqrt{233}}}\approx-2.07

The P-value = P(\overline{x}

Hence, the probability that the sample mean would be less than 137.01 liters is 0.0192 .

X^2 - 10x + 8 =0
x^2 - 10 + (-10/2)^2 - (-10/2)^2 + 8 = 0
(x - 5)^2 - 25 + 8 = 0
(x - 5)^2 - 17 = 0
To be honest , this is the final step for this equation. It seems like there is no any suitable answer for this question..
To me , I think the best answer will be the third option.
x - 5 =0
x = 5

2x-10 = 0
2x = 10
x = 5
I guess this answer seems like legit.. So I will choose the third option.

zheka24 [161]
2. a beverage company conducts a survey in the lobby of a health club to determine people's favorite beverage.

This question is biased, because certain drinks would be ruled out for being "unhealthy", such as soda, beer, etc. This means that healthier drinks, such as mineral water, electrolyte water, etc, would get more votes.
